🌸 std::uniform_real(3) 🌸

okay so bestie, welcome to the std::uniform_real page, straight out of the Library Functions Manual — yes that's the manual name, we're getting it out of the way early because this page is a whole vibe and we have things to read 💅

✨ NAME ✨

std::uniform_real — Uniform continuous distribution for random numbers. that's it, that's the pitch, and honestly? iconic.

🌸 Detailed Description 🌸

template<typename _RealType = double> class std::uniform_real< _RealType >

Uniform continuous distribution for random numbers. literally what it says on the tin, no notes 💖

so the way this works: it's a continuous random distribution on the range [min, max) — note the half-open bracket situation, bestie, min is in, max is out — with equal probability throughout the whole range. every value in there is equally likely, nobody's the favourite child 🫶

and hear me on this one: the URNG should be real-valued and deliver numbers in the range [0, 1). that's the requirement, don't come at it with something else, okay?? 😭

🧚 Constructor & Destructor Documentation 🧚

⭐ template<typename _RealType = double> std::uniform_real< _RealType >::uniform_real (_RealType __min = _RealType(0), _RealType __max = _RealType(1)) [inline, explicit]

Constructs a uniform_real object. yes bestie, we're building one, this is the moment 👑

Parameters:

  • ___min [IN] — The lower bound of the distribution.
  • ___max [IN] — The upper bound of the distribution.

💫 template<typename _RealType = double> template<typename _RealType1 , typename _CharT , typename _Traits > std::basic_ostream<_CharT, _Traits>& operator<< (std::basic_ostream< _CharT, _Traits > & __os, const uniform_real< _RealType1 > & __x) [friend]

Inserts a uniform_real random number distribution __x into the output stream __os. it's giving "let me introduce you to my friend, the stream" ✨

Parameters:

  • ___os — An output stream.
  • ___x — A uniform_real random number distribution.

Returns:

The output stream with the state of __x inserted or in an error state. (so either the data made it in, or the stream's having a bad day 💀)

🌟 template<typename _RealType = double> template<typename _RealType1 , typename _CharT , typename _Traits > std::basic_istream<_CharT, _Traits>& operator>> (std::basic_istream< _CharT, _Traits > & __is, uniform_real< _RealType1 > & __x) [friend]

Extracts a uniform_real random number distribution __x from the input stream __is. reading it back out, the reverse slay 🌸

Parameters:

  • ___is — An input stream.
  • ___x — A uniform_real random number generator engine.

Returns:

The input stream with __x extracted or in an error state.
